Tie Rod end
The rod end connect the center link to the steering knuckle on cars with conventional suspension systems and recirculating ball steering gears. On cars with MacPherson strut suspension and rack-and pinion steering gears, the rod ends connect the end of the rack to the steering knuckle. A rod end consists of an inner and an outer end. The rod end transmits force from the steering center link or the rack gear to the steering knuckle, causing the wheels to turn. The outer rod end connects with an adjusting sleeve, which allows the length of the rod end to be adjustable. This adjustment is used to set a vehicle’s toe a critical alignment angle.
